摘要： A system controls aspiration and dispensation of a liquid in a pipette. The system includes a computing device and the pipette. The computing device includes a pipetting module and a first communication interface. The pipetting module defines an operation to perform at the pipette. The first communication interface sends electronic signals to the pipette, the electronic signals defining the operation to perform at the pipette. The pipette includes a sampling tube, a piston assembly, a piston drive mechanism, a second communication interface, and a microprocessor. The piston assembly mounts to the sampling tube and includes a piston rod that fits within the sampling tube. The piston drive mechanism includes a control rod having a surface that contacts the piston assembly. The piston drive mechanism moves the piston rod of the piston assembly within the sampling tube thereby causing regulation of a liquid in the sampling tube. The second communication interface receives the electronic signals from the computing device. The microprocessor controls the piston drive mechanism and performs the operation defined by the electronic signals.

摘要： A pipette is provided having a reduced operational vibration and noise and an increased operational accuracy. The pipette includes a body and a drive unit mounted within the body. The drive unit includes a motor, an operating rod configured for movement under control of the motor, a nut, and an elastic strip. The nut is mounted to the operating rod and is configured to allow translational movement of the operating rod with respect to the nut, but not to allow rotational movement of the operating rod with respect to the nut. The elastic strip is mounted to the nut and to the body to exert a rotational torque on the nut.

摘要： A multivolume pipette is provided. In an exemplary embodiment, the multivolume pipette includes a pipette body, a piston disposed within the pipette body, a first chamber, a second chamber, and a valve. The first chamber and the second chamber are defined at least in part by an inner wall of the pipette body and the piston. The valve is capable of placing the second chamber in fluid communication with an external environment to provide a first volume range of the multivolume pipette. The valve is also capable of placing the second chamber in fluid communication with the first chamber to provide a second volume range of the multivolume pipette.
